Why do people not think Mcgregor is going to be TKO'ed / KO'ed in 2 rounds?

Just a thought to the people that say if Floyd wins then they wouldn't personally class it as 50-0 because it's a circus.

If Conor did somehow manage to land one big punch and knocks Floyd out then would you personally not class that as 49-1?

I would class it as the greatest upset of all time and the greatest day in the history of boxing.

Doesn't really answer the question at all does it
